This is the latest in DC's `big events' calendar, and carries on from the Sinestro Corps War and the subsequent spectrum of Lantern Corps, with back-ties to a number of past big events, and a spectacular resolution (or reset) to bring the Silver Age back to the centre-stage, with yet more resurrections, but this time with a reason, and a promise that this is the last of them (unless they realise that they have forgotten someone, I suppose).
At the end of the Sinestro Corps War, the Anti-Monitor's body was dumped on a planet in the forbidden space sector 666, and a black lantern grew around it. Here it is revealed that a being named Nekron has used it to power a corps of Black Lanterns to raise dead - or at least the physical remains of - people who were related to superheroes. This volume collects issues 0-8 of the main series of Blackest Night - other volumes featuring sub-sets of the heroes and their interaction with the Black Lanterns are also available.
The various Lantern Corps form a spectrum that can overpower the Black Lanterns, but the big secret that the Guardians of the Universe have been keeping is that there is a White power available, and the various Corps are the spectrum that makes up the white light. The Black Lanterns know where the White power has been hiding since it created the universe - and you can probably guess which planet it is on...
The story here is the initial Black Lantern attack on Earth, the gathering of forces, and the fight-back. It begins with a team-up story of the Flash and the Green Lantern, renewing their friendship, and ends with the White light resurrecting a number of currently dead heroes. During the course of the story we discover that Nekron claims to be responsible for the previous resurrections of Superman, Wonder Woman, Green Arrow, Green Lantern and the Flash, and others, and tries to convert them to Black Lanterns - succeeding with some of them. Eventually, his claim is disputed and he is defeated, but with a cost - resurrection of dead heroes!
The artwork is up to the task of depicting the action, as is the writing. For myself, the successive big events with skies crowded with characters and world- or even multiverse-shattering epics mean very little to me, as the writers have to come up with something bigger each time. Hopefully, now that the universe has been re-established and reset yet again, things will calm down...
